There are a number of alternative methods for providing income documentation other than the “Full Doc” method of submitting tax returns and W-2 statements.  A self-employed borrower often deducts as much as they can to reduce their tax liability.  Alternative methods can show their gross income minus a percentage of their business deductions, rather than an itemized list of business deductions.  Depending on the type of business, this percentage can often increase the calculated net income, and thereby increase the eligible loan amount.
